What are the items that the cartridge heater preset uses to pay attention to?
Let Jaye tell everyone about the pre-use of the production model cartridge heater. Pay attention to the items: the most widely used cartridge heater is the production model cartridge heater. The good production model cartridge heater preset can guarantee the production model order The life span of the heater.
1. The gap between the outer diameter of the model cartridge heater and its inserted aperture should be changed from large to small as much as possible. Generally, the gap between the two is less than 0.1-0.2mm. For example, a cartridge with a diameter of 10mm should be the pipe diameter within 10.2mm.
2. When machining the mounting hole, it should be effective to ensure its coaxiality and volume tolerance, such as using a reamer and other tools to trim the machining.
3. The residue left in the processing, such as organic oil, should be thoroughly cleaned up before installation of the heating pipe, which will be carbonized after heating, so there is experience in affecting heat conduction.
4. There will be no problem when using at the preset voltage. The actual power during use can be calculated according to the following formula: [Using voltage/preset voltage]*[Using voltage/preset voltage]*Preset i power = Power during operation (example) Electric heating tube with rated voltage and power of 230V 500W and operating voltage of 220V, its operating power is 418.6W, which is about 84% of the rated power.
